QA:Testcase nouveau 3D pymol

Description

A basic 3D rendering check using the PyMol molecular viewer. You must be using a card supported by the nouveau video driver.

Setup

1. Ensure the nomodeset and nouveau.modeset=0 kernel parameters are not set in your bootloader configuration
   • You can see your current kernel options by running cat /proc/cmdline
2. Ensure the file /etc/X11/xorg.conf does not exist, or is a valid file that uses the nouveau driver
3. Shut your system down entirely, then start it up again
4. If using a live image to test, ignore the above steps and simply boot the system from the live image with default options
5. Ensure that glxinfo | grep 'OpenGL renderer' does not return OpenGL renderer string: Software Rasterizer or llvmpipe
6. Install the pymol package with the command su -c 'yum install pymol'

How to test

1. Launch pymol from a terminal
2. Go to Wizard => Demo => Representations. There should be a list of demos on the right side of the Pymol viewer window
3. Click on each demo in turn. For each demo:
   1. Use the mouse wheel to increase or decrease complexity
   2. left-click+mouse to rotate
   3. middle-click+mouse to move around
   4. and right-click+mouse to zoom in/out
4. Quit pymol

Expected Results

1. All demos should run without crashing and tearing.
2. There should not be any obvious mis-renderings (flickering, surfaces that come and go...). Compare with reference screenshots below:
